Connecting Test Equipment to

the BTS: Overview

All test equipment is controlled by the LMF via IEEE–488/GPIB bus.

The LMF requires each piece of test equipment to have a factory set

GPIB address. If there is a communications problem between the LMF

and any piece of test equipment, verify that the GPIB addresses have

been set correctly (normally 13 for a power meter and 18 for a CDMA

analyzer).

This procedure requires working on our around circuitry

extremely sensitive to ESD. To prevent damage, wear a

conductive, high impedance wrist strap during handling of

any circuit board or module.

Follow appropriate safety measures.

CAUTION

Refer to Table 3-23 for an overview of connections for test equipment

currently supported by LMF.

Typical DIP switch positions and/or configurations are

shown in the following procedure and illustrations. If any

additional information is required, refer to the test

equipment OEM user manuals.
